ROLLBACK PREPARED transaction_id
- The transaction identifier of the transaction that is to be rolled back.
To roll back a prepared transaction, you must be either the same user that executed the transaction originally, or a superuser. But you do not have to be in the same session that executed the transaction.
This command cannot be executed inside a transaction block. The prepared transaction is rolled back immediately.
Roll back the transaction identified by the transaction identifier foobar:
ROLLBACK PREPARED 'foobar';
